Yann Arthus-Bertrand's documentary "Homeland"

In 2009, with the sponsorship of PPR, Yann Arthur filmed the environmental documentary "Homeland".

This documentary records the current state of the earth, climate, and the long-term impact of humans as the rulers of all things on the earth. The entire documentary expresses the theme of "interconnectedness"; all living things and the earth are in a "delicate but vital" natural balance with each other, and no living thing can be self-sufficient.

The first 15 minutes of the documentary show the origin of life in single-celled algae growing on the edge of volcanic hot springs. By showing the important role of algae in the evolution of photosynthesis, we explore the single-celled life form from which all plants today originate.

The next hour shows the Agricultural Revolution and its impact, and then the use of oil, leading to energy, industry, cities and the unprecedented gap between rich and poor. The documentary depicts the current crisis - feedlots, deforestation, food and water shortages, the use of non-renewable "fossil fuels", over-exploitation of resources and more. Cities such as New York City, Las Vegas, Los Angeles, Shenzhen, Mumbai, Tokyo and Dubai were also cited as examples of poor management and massive consumption of energy, water and food. A series of aerial shots of the Antarctic, Arctic and Africa show the demise of wetlands and glaciers, as well as the emergence of mass migration and refugees, and predict that this will continue to be the case. At this point, the film begins to focus on the crisis of global warming. Homes shows not only how melting glaciers, rising sea levels and climate change are ravaging people who have little to do with climate change, but will soon affect wealthy areas with large populations.

This documentary not only shows the terrible fact of mankind's destruction of the earth, but also describes the struggle and conservation measures mankind is taking: including renewable energy, more and more national parks, and various countries' efforts to protect the environment. International cooperation on matters, and the accompanying education and reforms, are already taking place around the world to address current global issues.
